The Science Behind 'Genetically Modified Humans'

The video discusses germ-line engineering, a method to modify genes in germ cells to prevent heritable diseases. It explains the CRISPR technology, which allows precise DNA editing, and its potential to replace mutated genes like BRCA1. However, germ-line engineering is controversial due to ethical concerns and risks of unintended mutations. While some countries ban it, researchers continue to explore its possibilities. Critics suggest alternative methods like in vitro fertilization and emphasize the need for public discourse before advancing human germ-line engineering.
